Some on-line games (for example: Half Life) will use lots of fragmented UDP packets to
transfer game data. Instinctively as a secure firewall, Vigor router will reject these
fragmented packets to prevent attack unless you enable “Accept Incoming Fragmented UDP
Packets”. By checking this box, you can play these kinds of on-line games. If security
concern is in higher priority, you cannot enable “Accept Incoming Fragmented UDP
Packets”.
